Provenance information Raw read quality was checked with FASTQC; adapters and low-quality reads were removed with Cutadapt. Trimmed reads were aligned to the bovine reference genome ARS-UCD1.2 with STAR (mean 90.62% mapped), and gene-level counts for protein-coding genes were generated using STAR "quantMode GeneCounts" against the Ensembl v87 annotation. Genes with <1 count per million in at least half the samples per comparison were removed; data were TMM-normalised and differential expression between H- and L-RFI steers was tested within each breed x diet comparison using exact tests in edgeR. A separate model evaluated the breed x diet interaction (RFI as class variable, animal as random effect). DEGs were defined as Benjamini-Hochberg FDR < 0.1 and fold change > 1.5 (230 DEGs across six comparisons; 23 interaction genes). DEGs were annotated and analysed for pathway enrichment using Ingenuity Pathway Analysis (Qiagen).
